This is the most bizarre map I've ever posted. I
never imagined I would have to label the
Azores--much less Portugal-- in a map for one of
our migrating Ospreys!
He left Rhode Island on the 7th, on a fine morning.
Unfortunately, he flew into a big front that was
moving up the coast.
As of the 10th, he had been out over the Atlantic for 4
days. for about 36 hours in the middle of that
period, he was on a ship--heading in very much
the wrong direction.
We did not expect to get any more signals from him, so
we were absolutely amazed when we got GPS
locations downloaded on the 14th.
As usual, scroll down for the details.

This is Chip's nest. Tim Bergquist, from
Chippers Inc. very skillfully put me up in the
nest to set our trap and extract the birds when
they were caught. (Thanks to Chippers for
providing the bucket truck!)
As so often happens, we caught the adult
female first. We just banded her and let her go.
We then waited a couple of hours before we
caught a young female (Jill) and then another 4
hours before we caught Chip. |

2-4 Aug 2012 -
Chip and Jill are staying pretty close to the
nest. |

2-4 Aug 2012 -
Chip is exploring quite a bit. This is a lot
different from the youngster (Saco) we tagged
last year. Saco never went more than 600 yards
from her nest until the day before she migrated.
The loop he made on 16 Aug got him to a point on
the Merrimack River 12 miles (19 km) south of
his nest. |

22 Aug 2012 -
Whoa! It appears Chip has started his migration.
If he keeps going south, rather than looping
around back to his natal area, this will be the
second earliest migration start of any of the 44
young we have tagged. The earliest was 19
August.
I've included the movements of all our New England
birds here. A few have been wandering a bit, but
no one else is making a move south. |
|
22-24 Aug 2012 -
It's official-Chip is heading south. It's likely
that he will stop along the way. Many of the
young we've followed will stop for extended
periods--sometimes a month or more--before
resuming migration. |

22-30 Aug 2012 -
Chip put the brakes on migration in Rhode
Island. He's on the Pettaquamscutt River, where
a few of our other tagged birds have spent some
quality time fishing.
No telling when he'll get going again. Juveniles
are remarkably unpredictable in their
migration--often stopping for a month or more in
the middle of their trip south.
It looked like he started migrating again on the 25th,
but if he did, something changed his mind. Maybe
the weather took a turn for the worse. With the
remnants of Isaac creeping up the eastern
seaboard as of this writing, it's unlikely he'll
move for a few days. Perhaps when the storm
moves through and a nice high pressure system
provides some northerly winds he'll get a move
on. |

22-30 Aug 2012 -
It would appear that the Pettaquamscutt is a
pretty fishy spot. The ponds are apparently (see
next map for details) full of bluegill,
pickerel, and small-mouth bass. The area where
Chip is doing most of his fishing is actually
brackish. |
|
Here's an old postcard of the
Pettaquamscutt River which is reportedly full of
white perch. Details on the river (and the
source of this picture):
http://bit.ly/Sjn2kt. The wooden structure
is unidentified--I think it is clearly a
prototype of a geodesic dome. Bucky Fuller must
have been fishing here and had some time on his
hands.
Update: Joe Scudlark gets the antique
fishing gear award for recognizing this strange
structure as a giant spool used to pull in
shore-based seine nets. |

1-25 Sep 2012 -
After his very early start to migration, Chip
seems to have forgotten what he set out to do,
which was not just to migrate to Rhode Island!
He's been here a little over a month now. This
is not that unusual for our juvie Ospreys. We've
often had them settle down for a month or more
before the migration urge kicked back in. It
certainly looks like Chip has found a great
fishing spot on Pettaquamscutt Lake. |

Photo Challenge! -
OK, Rhode Islanders, time to mount that
telephoto and head over to Lake Pettaquamscutt
and send me some pictures of Chip. So far this
year we've had pictures of Belle taken on
Martha's Vineyard and Thatch down in New Jersey.
We'd love a picture of Chip. He was there on the
25th, and it looks like we're not going to have
very good migration weather for a few days, so
it should be easy. Go for it!
-Update: we didn't get any pictures (just one
sighting), but did get reports that there are at
least 6 Ospreys fishing the lake! |

7-10 Oct 2012 -
After six weeks fishing the Pettaquamscutt, Chip
took off on the morning of the 6th on what
looked like the restart of his migration. Winds
were strong out of the southwest that day, so
maybe he decided it was too much effort and
retreated to the Pettaquamscutt. On the 7th, the
weather was pretty spectacular in the morning,
so Chip took off again, this time leaving a bit
after 8 AM. At 9 AM he was out over open water
just east of Block Island.b |
|
7-8 Oct 2012 -
Sometime during the day, the weather turned ugly
as a big low pressure system was working its way
up the coast. Chip flew into this storm sometime
in the afternoon. Our last signal on the 7th had
him tracking southwest-still on course and
seemingly in good shape. He had flown a
respectable 320 miles (522 km).
When his GPS unit turned on again at 9AM on the 8th, he
was 183 mi. (294 km) southwest of where he had
been the night before. Whatever course he took,
it wasn't the straight line shown on the map.

8 Oct 2012 -
This one's a challenge! We have no idea
how he got to where we pick him up at 9 AM.
Sometime after 9 he must have landed on a ship.
The 10 AM - 2 PM distances moved were too slow
for him to have been on the wing.
Then at 3 PM, he seems to be back in the air heading
southwest.
By 6 PM he had been out over the water for about 30
hours, and flown through some bad weather,
presumably. So maybe it's not too surprising
that when he saw another (?) ship he decided to
rest.
That's should have been OK, except the ship was heading
in the wrong direction--northeast. |

9-14 Oct 2012 -
This is crazy!
Back on the 10th I wrote that I would have been very
surprised to get any more signals from him, but
if we did, it wouldn't be the first time he has
surprised us! Consider us very surprised.
The question now is, of course, is he still alive, or
are we just tracking the ship? He's been out
over the Atlantic either on the wing or on board
his ship for a whole week.
And what exactly is this ship doing? I've got some
nautical experts on the case trying to figure
out if we can identify the ship.
There is a published report of an Osprey that spent
several days on a fishing boat 1,000 miles off
the west coast of South America (near the
Galapagos Islands). The bird would perch in the
rigging of the ship and foray out to catch fish,
returning to the ship to feed. Hard to imagine
poor young Chip pulling that off, but who knows?
Maybe the crew can open up a few cans of tuna for him! |

7-14 Oct 2012 -
Sadly, but not surprisingly, Chip didn't
make it. He died sometime on the 14th after 7
days out over the Atlantic--almost certainly
without eating that whole time.
So what was going on? We're confident that he was on at least
3 ships, and maybe 4.After being blown southeast
on the night of the 7th, he might has spent some
time on a ship on the 8th. Only problem with
that is that his average altitude during that
time was 185 m.
On the 9th he was absolutely on a ship. He was moving
in a perfectly straight line at only about 12
mph--too slow for an Osprey in flight.
It looks like he got off the ship on the 10th.and 11th.
If he was on a ship, it was one that was not
following a really tight compass course.
On the 12th he was on a ship again. If we extend the
bearing he was on, it matches the shipping lane
that would take a ship from the St. Lawrence to
southern Africa.
On the 13th he seems to have moved off one ship and
landed on another, this one on a course from the
Caribbean to Europe.
The last GPS signal from him was on the 14th. We did
get some weak signals from his radio on the
17th, but it was right where we last heard from
him on the 14th, so it appears his body was
floating out in the middle of the ocean.
What an amazing journey! |
